Thanks to the impending merger of Legg Mason Capital Management and ClearBridge Investments, Legg Mason [profile] is putting more of its office space on the market.

Eileen Ambrose of the Baltimore Sun reports that the Baltimore-based mutual fund shop plans to sublet an additional 78,000 square feet on three floors of its 372,000-square-foot headquarters. A Legg spokeswoman told the paper that the move was partly due to the merger of LMCM and New York City-based ClearBridge, announced last week.

According to the Sun, the Johns Hopkins Carey Business School and McGladrey already sub-let a combined 82,000 square feet of Legg's 372,000-square-foot headquarters and have done so since 2009. The new space will be available on April 1.

The move comes as Legg's board ponders whom to hire full-time as CEO.&nbsp
